2.10 Slower than 2.9.1 Version?

My project also experienced this; renders in version 2.9 never exceeded 15 minutes.

Shot 3_1.mp4 Render on Version 2.10 - 18 Minute

Hi there,

Path tracing simulates the way light naturally behaves in a scene by tracing the path of individual light rays. This creates more accurate lighting, shadows, and reflections, but it also requires more calculations, which leads to increased render times.
